Issue Description

I am encountering an issue where my HUION Tablet_H430P pen tablet is not functional within the Excalidraw plugin in Obsidian when running on Hyprland and GNOME both the environments. Specifically, I am unable to select or draw anything using the pen of my pen tablet within the Excalidraw plugin. However, I am able to use the mouse without any issues. Notably, The pen tablet was functioning correctly in Obsidian up till 23rd July 2024.

Steps to Reproduce

  • Install Obsidian via Flatpak on Fedora Unix Linux with Hyprland (Wayland) or GNOME as the window manager.
  • Open Obsidian and enable the Excalidraw plugin.
  • Attempt to use the HUION Tablet_H430P pen tablet within the Excalidraw plugin.

Did you follow the troubleshooting guide? [Y/N]

Yes i did the above given steps in the sandbox vault

Expected result

I expect to be able to use my pen tablet to draw and interact with elements within the Excalidraw plugin, similar to how it functions with a mouse.

Actual result

The pen tablet is not responsive within the Excalidraw plugin. I am unable to select or draw anything using the pen. However, the pen tablet works correctly in other applications and even in standalone Excalidraw instances outside of Obsidian.

I am happy to report that i have found a workaround for this bug i encountered and here are the steps we can follow

  • Downgrade the Kernel: Downgrade the kernel version to anything below 6.9.12-200.fc40.x86_64 ( I am personally on the kernel version 6.9.11-200.fc40.x86_64)

  • Sandbox Permissions: Apply the following Sandbox Permissions

     [Context]
 shared=network;ipc;
 sockets=x11;pulseaudio;fallback-x11;ssh-auth;
 devices=dri;
 filesystems=/home/tratum/.themes;/mnt;xdg-run/app/com.discordapp.Discord:create;/home/tratum/.icons;xdg- 
 run/gnupg:ro;/run/media;home;/media;~/.local/share/fonts:ro;
 persistent=~/.ssh;

 [Environment]
 GTK_THEME=Andromeda-dark
 SSH_ASKPASS=/app/libexec/openssh/ssh-askpass
 OBSIDIAN_ENABLE_AUTOSCROLL=0
 PATH=/usr/bin:/app/bin:/app/texlive/bin:/app/texlive/bin/x86_64-linux:/app/texlive/bin/aarch64-linux
 OBSIDIAN_DISABLE_GPU=0
 GH_PATH=gh
 OBSIDIAN_CLEAN_CACHE=1
 XCURSOR_PATH=/run/host/user-share/icons:/run/host/share/icons:~/.icons
 ICON_THEME=Flat-Remix-Blue-Dark

Note: Unfortunately This’ll not work for wayland and only the x-11-windowing system via the gnome desktop environment
